一、C++服务器端
（用的是Visual Studio 2008（05，03的应该也可以，VC++的可能需要稍微改动））
代码如下：
#include <winsock2.h>
#include <stdio.h>
#include <windows.h>
#include <iostream>
using namespace std;
#pragma comment(lib,"ws2_32.lib")
 
void main(){ 
 WORD wVersionRequested;
 WSADATA wsaData;
 int err;
 short port=1300;//端口号
 
 wVersionRequested = MAKEWORD( 1, 1 );
 
 err = WSAStartup( wVersionRequested, &wsaData );//初始化套接字
 if ( err != 0 )
 {
    return;
 }
 
 if ( LOBYTE( wsaData.wVersion ) != 1 || HIBYTE( wsaData.wVersion ) != 1 )
 {
    WSACleanup( );
    return;
 }
 
 SOCKET sockSrv=socket(AF_INET,SOCK_STREAM,0);//创建套接字
 SOCKET sockConn;//用来和客户端通信的套接字
 
 SOCKADDR_IN addrSrv;//用来和客户端通信的套接字地址
 
 addrSrv.sin_addr.S_un.S_addr=htonl(INADDR_ANY);
 addrSrv.sin_family=AF_INET;
 addrSrv.sin_port=htons(port);
 
 bind(sockSrv,(SOCKADDR*)&addrSrv,sizeof(SOCKADDR));//绑定端口
 
 listen(sockSrv,5);//侦听
 
printf("Server %d is listening......\n",port);
 
 SOCKADDR_IN addrClient;
 
 int len=sizeof(SOCKADDR);
 
char buf[4096];//接收的数据
char rbuf[100]="成功";//返回的数据
 
 while(1)
 {
        //接受连接
         sockConn=accept(sockSrv,(SOCKADDR*)&addrClient,&len);
         printf("Accept connection from %s\n",inet_ntoa(addrClient.sin_addr));
 
         //接收数据
         int bytes;
         if((bytes=recv(sockConn,buf,sizeof(buf),0))==SOCKET_ERROR){
              printf("接收数据失败!\n");
              exit(-1);
         }
         buf[bytes]='\0';
         printf("Message from %s: %s\n",inet_ntoa(addrClient.sin_addr),buf);
 
         //发送数据
        if(send(sockConn,rbuf,strlen(rbuf)+1,0)==SOCKET_ERROR){
              printf("发送数据失败！");
              exit(-1);
         }
        printf("Message to %s: %s\n",inet_ntoa(addrClient.sin_addr),rbuf);
 
        //清理套接字占用的资源
        closesocket(sockConn);
 }
 
 
}
 
运行效果如下：

二、Flex客户端（Flex Builder）
代码如下
<?xml version="1.0" encoding="utf-8"?>
<mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"
     creationComplete="initApp();">
        <mx:Script>
        <![CDATA[
            import flash.net.Socket;
            private var socket:Socket;
            private function initApp():void
            {
             
            }
           
            private function StartTest():void
            {         
              socket = new Socket("127.0.0.1",1300);     
                socket.addEventListener(Event.CONNECT, connectHandler);
                socket.addEventListener(ProgressEvent.SOCKET_DATA, socketDataHandler);
            }
            private function CloseTest():void
            {   
                if(socket!=null && socket.connected)
                {
                    trace("socket.connected:"+socket.connected);
                    socket.close();
                    trace("socket.connected:"+socket.connected);
                }
            }
            private function connectHandler(event:Event):void
            {
                trace("connectHandler: " + event);
                socket.writeMultiByte(SendStr.text,"GB2312");               
                socket.flush();
            }
            private function socketDataHandler(event:ProgressEvent):void
            {
                trace("socketDataHandler: " + event);
                var str:String=socket.readMultiByte(socket.bytesAvailable,"GB2312");
                ReceiveStr.text = str;
            }
        ]]>
    </mx:Script>
 
        <mx:Text text="发送" y="11" x="18" fontWeight="bold" color="#ffffff"/>
        <mx:TextArea id="ReceiveStr" x="53" y="68"/>
        <mx:Text text="接收" y="69" x="18" fontWeight="bold" color="#ffffff"/>
        <mx:TextArea id="SendStr" y="10" x="53"/>

三、运行
先运行C++服务器端，再运行Flex客户端，成功后如下图所示利用Socket实现C++与Flex通信_职场_02
